This PR adds deprecation warnings when accessing System Indices via the REST layer. At this time, these warnings are only enabled for Snapshot builds by default, to allow projects external to Elasticsearch additional time to adjust their access patterns.
Deprecation warnings will be triggered by all REST requests which access registered System Indices, except for purpose-specific APIs which access System Indices as an implementation detail a few specific APIs which will continue to allow access to system indices by default:
- `GET _cluster/health`
- `GET {index}/_recovery`
- `GET _cluster/allocation/explain`
- `GET _cluster/state`
- `POST _cluster/reroute`
- `GET {index}/_stats`
- `GET {index}/_segments`
- `GET {index}/_shard_stores`
- `GET _cat/[indices,aliases,health,recovery,shards,segments]`
Deprecation warnings for accessing system indices take the form:
```
this request accesses system indices: [.some_system_index], but in a future major version, direct access to system indices will be prevented by default
```
Backport of #59293 to 7.x branch.
* Create new data-stream xpack module.
* Move TimestampFieldMapper to the new module,
this results in storing a composable index template
with data stream definition only to work with default
distribution. This way data streams can only be used
with default distribution, since a data stream can
currently only be created if a matching composable index
template exists with a data stream definition.
* Renamed `_timestamp` meta field mapper
to `_data_stream_timestamp` meta field mapper.
* Add logic to put composable index template api
to fail if `_data_stream_timestamp` meta field mapper
isn't registered. So that a more understandable
error is returned when attempting to store a template
with data stream definition via the oss distribution.
In a follow up the data stream transport and
rest actions can be moved to the xpack data-stream module.
I've noticed that a lot of our tests are using deprecated static methods
from the Hamcrest matchers. While this is not a big deal in any
objective sense, it seems like a small good thing to reduce compilation
warnings and be ready for a new release of the matcher library if we
need to upgrade. I've also switched a few other methods in tests that
have drop-in replacements.
ML mappings and index templates have so far been created
programmatically. While this had its merits due to static typing,
there is consensus it would be clear to maintain those in json files.
In addition, we are going to adding ILM policies to these indices
and the component for a plugin to register ILM policies is
`IndexTemplateRegistry`. It expects the templates to be in resource
json files.
For the above reasons this commit refactors ML mappings and index
templates into json resource files that are registered via
`MlIndexTemplateRegistry`.
Backport of #51765
Previously this test failed waiting for yellow:
https://gradle-enterprise.elastic.co/s/fv55holsa36tg/console-log#L2676
Oddly cluster health returned red status, but there were no unassigned, relocating or initializing shards.
Placed the waiting for green in a try-catch block, so that when this fails again then cluster state gets printed.
Relates to #48381
The timeout was increased to 60s to allow this test more time to reach a
yellow state. However, the test will still on occasion fail even with the
60s timeout.

7.5+ for SLM requires [stats] object to exist in the cluster state.
When doing an in-place upgrade from 7.4 to 7.5+ [stats] does not exist
in cluster state, result in an exception on startup [1].
This commit moves the [stats] to be an optional object in the parser
and if not found will default to an empty stats object.

With this change the test setup for ML config upgrade
tests only waits for v6.6+ ML index templates to be
installed if the old cluster is running version 6.6.0
or higher.
Previously it was always waiting, but timing out without
failing the test if the templates were not installed
within 10 seconds, effectively just adding a pointless
10 second sleep to BWC tests against versions earlier
than 6.6.0. This problem was exposed by #47112.
Fixes#47286
This commit adds a first draft of a regression analysis
to data frame analytics. There is high probability that
the exact syntax might change.
This commit adds the new analysis type and its parameters as
well as appropriate validation. It also modifies the extractor
and the fields detector to be able to handle categorical fields
as regression analysis supports them.
In hamcrest 2.1 warnings for unchecked varargs were fixed by hamcrest using @SafeVarargs for those matchers where this warning occurred.
This PR is aimed to remove these annotations when Matchers.contains ,Matchers.containsInAnyOrder or Matchers.hasItems was used
backport #41528
The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.
This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed. And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit). This arrangement is very
error-prone for users.
This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.
The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.
The change applies to both REST and java clients.
This commit removes xpack dependencies of many xpack qa modules.
(for some qa modules this will require some more work)
The reason behind this change is that qa rest modules should not depend
on the x-pack plugins, because the plugins are an implementation detail and
the tests should only know about the rest interface and qa cluster that is
being tested.
Also some qa modules rely on xpack plugins and hlrc (which is a valid
dependency for rest qa tests) creates a cyclic dependency and this is
something that we should avoid. Also Eclipse can't handle gradle cyclic
dependencies (see #41064).
* don't copy xpack-core's plugin property into the test resource of qa
modules. Otherwise installing security manager fails, because it tries
to find the XPackPlugin class.
* [ML] Addressing bug streaming DatafeedConfig aggs from (<= 6.5.4) -> 6.7.0 (#40610)
* Addressing stream failure and adding tests to catch such in the future
* Add aggs to full cluster restart tests
* Test BWC for datafeeds with and without aggs
The wire serialisation is different for null/non-null
aggs, so it's worth testing both cases.
* Fixing bwc test, removing types
* Fixing BWC test for datafeed
* Update 40_ml_datafeed_crud.yml
* Update build.gradle
The Migration Assistance API has been functionally replaced by the
Deprecation Info API, and the Migration Upgrade API is not used for the
transition from ES 6.x to 7.x, and does not need to be kept around to
repair indices that were not properly upgraded before upgrading the
cluster, as was the case in 6.
Instead of using `WarningsHandler.PERMISSIVE`, we only match warnings
that are due to types removal.
This PR also renames `allowTypeRemovalWarnings` to `allowTypesRemovalWarnings`.
Relates to #37920.
This commit adds the 7.1 version constant to the 7.x branch.

We have had various reports of problems caused by the maxRetryTimeout
setting in the low-level REST client. Such setting was initially added
in the attempts to not have requests go through retries if the request
already took longer than the provided timeout.
The implementation was problematic though as such timeout would also
expire in the first request attempt (see #31834), would leave the
request executing after expiration causing memory leaks (see #33342),
and would not take into account the http client internal queuing (see #25951).
Given all these issues, it seems that this custom timeout mechanism
gives little benefits while causing a lot of harm. We should rather rely
on connect and socket timeout exposed by the underlying http client
and accept that a request can overall take longer than the configured
timeout, which is the case even with a single retry anyways.
This commit removes the `maxRetryTimeout` setting and all of its usages.
`waitForRollUpJob` is an assertBusy that waits for the rollup job
to appear in the tasks list, and waits for it to be a certain state.
However, there was a null check around the state assertion, which meant
if the job _was_ null, the assertion would be skipped, and the
assertBusy would pass withouot an exception. This could then lead to
downstream assertions to fail because the job was not actually ready,
or in the wrong state.
This changes the test to assert the job is not null, so the assertBusy
operates as intended.
This commit adds deprecation warnings for index actions
and search actions when executed via watcher. Unit and
integration tests updated accordingly.
relates #35190
Migrate ml job and datafeed config of open jobs and update
the parameters of the persistent tasks as they become unallocated
during a rolling upgrade. Block allocation of ml persistent tasks
until the configs are migrated.
In Lucene 8 searches can skip non-competitive hits if the total hit count is not requested.
It is also possible to track the number of hits up to a certain threshold. This is a trade off to speed up searches while still being able to know a lower bound of the total hit count. This change adds the ability to set this threshold directly in the track_total_hits search option. A boolean value (true, false) indicates whether the total hit count should be tracked in the response. When set as an integer this option allows to compute a lower bound of the total hits while preserving the ability to skip non-competitive hits when enough matches have been collected.
